Weaver 48400 Multi-Slot Extended Base Savage Axis I/II Black

The Weaver 48400 Multi-Slot Base transforms Savage Axis I/II rifles manufactured after June 2021 into versatile platforms ready for serious optics mounting. This extended aluminum base provides the additional rail space needed for larger scopes and tactical accessories while maintaining the rock-solid mounting integrity Weaver is known for.

What Makes This Different

Unlike standard short bases that limit scope positioning options, this extended design offers multiple mounting positions along its length. The multi-slot configuration allows precise scope placement for optimal eye relief and cheek weld, particularly important with variable power optics. The black anodized aluminum construction resists corrosion while adding minimal weight to the rifle system.

Key Features

• Extended length design provides multiple scope mounting positions
• Multi-slot Weaver/Picatinny rail pattern for universal ring compatibility
• Precision-machined 6061-T6 aluminum construction for strength and durability
• Black anodized finish resists wear and environmental exposure
• Direct bolt-on installation to factory receiver holes
• Compatible with Savage Axis I and Axis II rifles manufactured post-June 2021
• Low-profile design maintains clean rifle lines

This base handles everything from lightweight hunting scopes to heavy tactical optics without flexing or shifting under recoil. The extended platform proves particularly valuable when mounting large objective scopes that require specific positioning for proper eye relief. hunters appreciate the flexibility to optimize scope placement for different shooting positions, while precision shooters benefit from the solid foundation for repeatable zero retention.
